IBM Aptiva 2142 - Manual (Page 161)

CD/DVD-ROM Drive Jumper Settings
The CD/DVD-ROM drives are connected to the system board secondary
drive connector at the factory. CD/DVD-ROM drive jumpers are set as the
master drive, as shown in Figure 5-11. If an additional hard disk drive is
connected to the secondary connector, it must be set as the master drive
(see
1 in figure 5-7) and the CD/DVD-ROM drive jumpers reset as the
slave drive as shown in Figure 5-11.
Note: For models that have a factory-installed Zip drive, the Zip drive is
jumpered as slave and the CD/DVD-ROM drive is jumpered as master. See
“Zip Drive” on page 5-14
Check the Setup Utility for correct installation.
